ECorrespondenceStrategy determines the basic approach that will be used to establish a mapping from points on the BakeTarget Mesh (usually low-poly) to points on the Detail Mesh (eg highpoly). Geometrically this is not a 1-1 mapping so there are various options
enum ECorrespondenceStrategy { RaycastStandard, NearestPoint, RaycastStandardThenNearest, Identity, Custom, }
